根据20世纪世纪日本海海底溶解氧（O-2）的减少趋势，推断出日本海深海环流（传送带）的减弱。这一趋势表明，由于传送带太不活跃，无法补偿海底的生物O-2消耗，O-2供应缩短。日本海北方冬季的近期气候变化可能在阻止表层海水密度足以下沉到底部的形成方面发挥了重要作用。据预测，日本海的底层水将在几百年内变得缺氧，就像它在最后一次冰期最大。
Weakening of the abyssal circulation (conveyor belt) in the Japan Sea during the 20th century is deduced from the decreasing trend of bottom dissolved oxygen (O-2). This trend indicates a shortened O-2 supply, caused by too inactive conveyor belt to compensate for biological O-2 consumption at the bottom of the sea. Recent climatic changes during the winter season in the northern Japan Sea may play a significant role in prohibiting the formation of surface seawater dense enough to sink to the bottom. It is predicted that the Japan Sea bottom water will become anoxic within a few hundred years, as it was in the last glacial maximum.
